The aim of this paper is to introduce, in broad strokes, a framework – constructed from a fusion of granular flow (GFD)  dynamics, tribology and computational fluid dynamic (CFD) techniques – for the practical analysis of mass finishing processes.
The granular fluid rheology model equations may be used to close the continuum continuity and momentum equations: ∂ρ∂t + ∂ρuj∂xj=0 (6a) ∂ρui∂t+∂uiuj∂xi=∂σij∂xj+ρfi (6b) so that is possible to solve for the media flow field using a general purpose CFD software code such as ANSYS CFX or ANSYS Fluent.
